Streblote cristata
In 3 days ~10% in a week ~20%
Streblote cristata is a species of moth in the family Lasiocampidae, the so-called eggars, snout moths or lappet moths. The species was first described by Caspar Stoll in 1782. Streblote cristata occurs in the fynbos of the far south Western Cape Province of South Africa, where it has been observed on fynbos species such as members of the Podalyria and Erica genera. It also has been found on domestic thyme. Such a varied range of food plants, but without much tendency for any single larva to migrate to a different species during its development, is common among the Lasiocampidae. Wikipedia →

Rare
Under 5% of wildlife watchers report a Crested Nadiasa sighting in Cape Town on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 165th most-seen of the 311 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
February, August and October
In those months about 10% of wildlife watchers report a Crested Nadiasa in Cape Town on a given day, against under 5% in March–July, September and November–January, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Crested Nadiasa sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Cape Town, in our data
Cape Town is the only city on Wallace's Line with enough records to rate Crested Nadiasa sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Lasiocampidae
The closest relatives of the Crested Nadiasa that you can see in Cape Town (family Lasiocampidae, Lappet Moths) are Cape Lappet (about 20%), Mountain White-Spot (about 10%) and Barred Eggarlet (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Crested Nadiasa is recorded against all the insects logged in Cape Town (18 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
